Question

This part insulates the reaction chamber from the transfer of heat to or from the surrounding environment. this part contains a known amount of water, which is placed there before the experiment starts. this part is where the metal is placed at the beginning of the experiment. this part is used for measuring the initial and final temperatures of the water.

Answer 1

The amount of heat transferred in and out of the system is measured by calorimetry. The thermometer in the calorimeter is used to measure the temperature.

What are the parts of the calorimetry device?

The thermometer (A) is a device used to measure the final and the initial temperature of the water or any other liquid in a system. A metal vessel is a place where the reaction mixture is present.

In-vessel (B), water, and metal are placed before the beginning of the experiment. The styrofoam cup or the outer metal vessel (C) insulates the instrument, from regulating the heat transformation.

Therefore, part A measures the temperature of the reaction mixture.
